In particular, it relates to a single-bearing reel provided with a braking mechanism.

[0002]

2. Description of the Related Art In general, a single-bearing reel is provided with a clutch and a braking mechanism. When a fishing line is sent out, a clutch is actuated to prevent a backlash, a line entanglement, etc., and a brake is applied to the rotation of a spool. Some have been proposed (JP-A-57-144924, JP-A-2-199325).

[0003]

However, in the conventional single-bearing reel, since the braking mechanism is provided on the reel body, the reel body tends to be large.

[0004] The present invention has been made in view of the above-described problems, and without increasing the size of the reel body,
It is an object of the present invention to provide a single-bearing reel that can effectively use the space of a hollow portion of a spool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of a single-bearing reel according to the present invention. In the drawing, reference numeral 1 denotes a reel body, on which a spool shaft 2 is fixed so as not to rotate. A first gear 3 and an embedded metal 4 are rotatably fitted to the spool shaft 2. Here, the first gear 3 and the embedded metal 4 are engaged so that the rotation is integrated as shown in FIG. That is, in FIG.
Is provided with a flange 3a, and an engagement recess 3b is formed in the flange 3a. In addition, 4
An engagement protrusion 4a is formed at the end of the first member, and the engagement protrusion 4a is configured to be integrally rotated by being engaged with the engagement recess 3b. On the other hand, the teeth 3c of the first gear 3 are meshed with small-diameter teeth 7a of a second gear 7 rotatably supported via a washer 5 and a pin 6 on a support 1a projecting from the reel body 1. ing.

Further, the large-diameter tooth portion 7b of the second gear 7 meshes with a tooth portion 8a of a clutch cover 8 rotatably fitted on the outer periphery of the flange portion 3a of the first gear 3. Here, the number of teeth of the teeth 3 c of the first gear 3, the number of teeth of the small diameter gear 7 a and the number of teeth of the large diameter gear 7 b of the second gear 7, and the number of teeth of the teeth 8 a of the clutch cover 8 are determined by the rotation of the first gear 3. The number is appropriately set so that the number of rotations of the clutch cover 8 becomes larger than the number of rotations.

On the other hand, the hub 9a of the spool 9 is rotatably fitted into the metal filling 4 with a gap in the axial direction between the clutch cover 8 and the spool shaft 2. This spool 9
Is fixed via a side wall 9c. A wall 9 for forming a clutch mechanism housing 9d on the clutch cover 8 side (the left side in FIG. 1) is provided at an appropriate position on the side wall 9c.
e is protruding. The end of the wall 9e is fixed to the clutch cover 8 by a screw (not shown), and the rotation of the clutch cover 8 is transmitted to the spool 9.

[0010] A one-way clutch 10 is fitted into the padding 4 in a gap between the hub 9 a of the spool 9 and the clutch cover 8. Further, a clutch holder 11 is integrally fitted to an outer peripheral portion of the one-way clutch 10. Here, the one-way clutch 10 is set so that the clutch is not operated and the rotational force is not transmitted when the fishing line rotates in the winding direction, and the clutch is activated and the rotational force is transmitted when the fishing line is rotated in the payout direction. . A tooth portion 11a is formed on an outer peripheral portion of the clutch holder 11.

On the left side of the side wall 9c of the spool 9 in FIG. 1, a cylindrical wall 9f having an open end protrudes from the side wall 9c, thereby forming a brake mechanism housing 9g. Then, the brake adjusting screw 12 penetrates through a through hole 9h formed in the side wall 9c. A male screw is formed on the shaft of the brake adjusting screw 12, and a drag nut 13, whose rotation is suppressed, is screwed onto the male screw. The drag nut 13 is adjusted in accordance with the screwing operation of the brake adjusting screw 12. Reference numeral 13 is screwed so as to be movable in the left-right direction in the figure, and the brake adjusting screw 12 closes the opening of the wall 9f. Further, the brake adjusting screw 12
A stop ring 14 is provided at the tip of the brake nut 12 to prevent the drag nut 13 from coming off the brake adjusting screw 12. The drag nut 13 and the side wall 9c of the spool 9 are also provided.
, A compression coil spring 15 is interposed therebetween, and constantly urges the drag nut 13 to the left in FIG.
The brake adjusting screw 12 is prevented from rattling in the axial direction.

A brake gear 16 is rotatably provided on the outer periphery of the drag nut 13. The brake gear 16 is meshed with a tooth portion 11a formed on the clutch holder 11. Drag washers 17, 17 are disposed at both ends of the brake gear 16, and a drag washer 17 located on the right side of the brake gear 16 in FIG. Reference numerals 17 are in contact with the drag nuts 13, respectively.

On the other hand, a hole 18a formed in one end of the handle 18 is inserted into the right side of the filling metal 4 in FIG. Here, the rotation of the handle 18 with respect to the embedded metal 4 is suppressed. As shown in FIG. 3, a push button 19 is provided at one end of the handle 18 and is constantly urged downward in FIG. 3 by a coil spring 20 housed in a hollow portion 18b of the handle 18. Have been.
The push button 19 is provided with a hole 19a. The hole 19a is engaged with a circumferential engagement groove 2a formed at the right end of the spool shaft 2 in FIG.
Is prevented from falling off. In addition, this handle 1
A grip 22 is fixed to the other end of 8 by a screw 21.

The speed-increasing mechanism in the present specification is composed of a metal filling 4, a first gear 3, a second gear 7, and a clutch cover 8 in the above embodiment. In the above-described embodiment, the brake mechanism is provided with the brake gear 16, the drag washer 17, the drag nut 13, the brake adjusting screw 12,
It is composed of a compression coil spring 15.

The operation of the thus configured single bearing reel will be described below. When winding the fishing line, the handle 18 is rotated in the winding direction while holding the grip portion 22. Then, since the rotation of the handle 18 with respect to the embedded metal 4 is suppressed, the embedded metal 4 also rotates. Thereby, the first gear 3 also rotates, and this rotation is transmitted to the second gear 7 and the clutch cover 8. Then, the rotation of the clutch cover 8 is transmitted to the spool 9. At this time, since the number of teeth of each tooth portion is set so that the number of rotations of the clutch cover 8 is larger than the number of rotations of the first gear 3, the number of rotations of the spool 9 is larger than the number of rotations of the handle. . Therefore, it is possible to wind the fishing line quickly. At this time, rotation is not transmitted from the deposit 4 to the one-way clutch 10, and the braking mechanism does not operate.

In the case where the fishing line is pulled by the fish or the fishing line is fed out artificially, the spool 9 rotates in the direction opposite to the winding direction. At this time, the rotation of the spool 9 is transmitted to the clutch cover 8, the second gear 7, the first gear 3, and the embedded metal 4 at a reduced speed. Further, the rotation of the filling metal 4 causes the clutch holder 11 to rotate by the operation of the one-way clutch 10. Here, this clutch holder 1
The difference between the number of rotations of 1 and the number of rotations of the spool 9 is mechanically absorbed by the rotation of the brake gear 16, but the brake gear 16 is now braked by a drag nut 13 and a drag washer 17. Therefore, the brake gear 16 cannot rotate freely. As described above, since the brake gear 16 is braked, the difference in the number of rotations between the clutch holder 11 and the spool 9 cannot be sufficiently absorbed, and the rotation of the spool 9 is braked. . For this reason, at the time of feeding, backlash, thread entanglement and the like can be prevented.

The braking force applied to the brake gear 16 is adjusted by the brake adjusting screw 12. That is, when the brake adjusting screw 12 is rotated counterclockwise and the drag nut 13 is moved to the left in FIG. 1, the pressing force by the drag nut 13 and the drag washer 17 is relaxed, and the braking force does not increase. Screw 12
Is rotated clockwise and the drag nut 13 is moved to the right in FIG. 1, the pressing force on the brake gear 16 is increased, and the braking force is increased.

When the handle 18 is to be removed from the reel body, the push button 19 in FIG. 3 is moved upward in the figure against the urging force of the coil spring 20 so as to be in the position indicated by the two-dot chain line in FIG. . For this reason, the hole 19a is
Remove from a. In this state, the handle 18 can be moved rightward in FIG. 1 and can be removed from the reel body.

In the above-described embodiment, the description has been made assuming that the speed increasing mechanism is provided. However, the speed increasing mechanism is not always necessary, and may be omitted.

[0020]

According to the present invention, as described above, the rotation of the spool can be braked when the fishing line is paid out, so that backlash and line entanglement can be prevented. Further, since the braking mechanism is housed inside the winding body of the spool, there is no need for a space for installing the braking mechanism, and it is possible to prevent an increase in the size of the device.
